AOSP - networkAttributes 中 CSV 的含义

Question

networkAttributes 的项目包含逗号分隔列表：

<string-array translatable="false" name="networkAttributes">  
  <item>"wifi,1,1,1,-1,true"</item>  
  <item>"ethernet,9,9,9,-1,true"</item>
</string-array>

值 "wifi,X,Y, ..." 是什么意思？

Answer 1

构造函数采用这些值，位于此处：platform/frameworks/base/core/java/android/net/NetworkConfig.java

看起来像这样：

 /**
 * input string from config.xml resource.  Uses the form:
 * [Connection name],[ConnectivityManager connection type],
 * [associated radio-type],[priority],[dependencyMet]
 */
public NetworkConfig(String init) {
    String fragments[] = init.split(",");
    name = fragments[0].trim().toLowerCase(Locale.ROOT);
    type = Integer.parseInt(fragments[1]);
    radio = Integer.parseInt(fragments[2]);
    priority = Integer.parseInt(fragments[3]);
    restoreTime = Integer.parseInt(fragments[4]);
    dependencyMet = Boolean.parseBoolean(fragments[5]);
}

它用在几个地方，例如： platform/frameworks/opt/telephony/src/java/com/android/internal/telephony/dataconnection/DcTracker.java 方法中 private void initApnContexts()

此致！
